TAKING-OFF DISK FOR FEEDING IPAPER IN PRINTING AND THE LIKE MACHINES.

Specification of Letters Patent.

Patented March 6, 1906.

To all whom, it may concern:

Be it known that we, JAMES HALL, a resident of 308 Gorton road, Reddish, and MAXI- MILIAN THOMAS BARBER, a resident of 14 Cumberland street, Manchester, county of Lancaster, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Taking-Oif Disks for Feeding Pa er in Printing and the Like Machines; an we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it aplpertains to make and use the same.

T e said invention is an im I rovement on the subject of Letters Patent Maximilian T. Barber, dated December 30, 1902; and it consists in the construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of one of the feeddisks and proximate parts embodying our invention, the shaft with which the said disk rotates being shown in cross-section and the feed-roller raised out of operative position. Fig. 2 represents a section on the line a w of Fig. 1; and Fig. 3 is similar to Fig. 1, but shows the said roller in contact with the pile of paper sheets for feeding the same.

In the patent above mentioned a fixed eripheral pad is carried by the transverse ymoving and rotating feed-disk for thus taking off sheets successively from the pile. In the present improvement we substitute therefor a roller d, suitably coated on the eriphery and mounted on the feeding-disk (l so as to project beyond the circumference of the latter. The said roller is provided with a ratchet-wheel engaged by a retaining-pawl d pivoted on the said disk and arran ed to prevent the said roller from rotatin when in contact with thesheet and carrie forward by the rotation of the shaft q and the said dis When not in operation, the said roller may, however, be easlly adjusted by hand to bring another part of its eriphery into position for such contact. T e said feeding-disk d is pivoted on one side atd to a carrier'disk or plate (1 fast at its center to the rotating shaft q, and the former disk is ada ted to drop by gravity sufliciently below t e said carrier-disk for contact of the said roller with Flg. 3, whenever the said roller approaches the lowest point of its revolution with said feeding-disk. Diametri'cally opposite pivot d is a connecting and guiding rod d screwthreaded for a part of its length and pivoted at one end on a stud d of the said carrier disk or plate, its other end being movable through a lug d on the feeding-disk A spring (1 is interposed between the latter lug and a nut d on said rod.

When the parts are in the operative posi tion (shown in Fi 3) the said spring bearing upward a ainst t e lu d on the, relatively movable eeding-disk tends to lift the latter and lighten its pressure on the paper,. thus resisting the action of gravity aforesaid. Such resistance may be increased or diminished by adjusting the said nut on the said as required, the pressure of the roller eing thus-adapted at will to the lightnessor heaviness of the paper. In this position the weight of the feeding-disk on the side opposite the pivot d is partly borne by the pile of paper, partly by the said spring, and (through nut d and rod d by the stud d and carrier plate or disk (i As the said shaft and disks continue to revolve in the direction of the arrow the roller 01 passes up out of contact with the pa er, the rod (1 is pulled gradually througli lug d relieving the spring (i from tension, the nut (1 reaches into the same horizontal plane as lug (1 then passes above it, attaining the position shown in Fig. 1, the disk (1 simultaneously swin 'ng over on its 'pivot (1 until concentric wit carrier disk or plate (1 with the rollerd vertically above the shaft 9 and projecting but slightl above the said carrier-disk. The continue rotation of shaft g and .the said disks'will bring the parts gradually around again into the position shown in Fig. 3, the spring (i meanwhile resisting the independent downward and for ward movement of feeding-disk d.

This improvement thus provides a very delicate means of adjustment of the pressure of the feeding-surface to the quality and requirement of the material to be operated on. Having thus described our inventlon, what we claim as new, and desire to secure by Letters Patent, is

1. In combination with a rotary carrier the upper sheet of the paper pile, as shown inv ICC disk or plate, a feeding-disk rotating there- Workin through a lug on the other, a nut on with but connected thereto for independent said ro and a spring adjustable by said nut I 5 transverse, gravitating movement, a spring and arranged to support the said feeding-' arranged to resist said independent movement i disk a ainst gravity to a degree determined and means for adjusting the tension and reby said nut substantially as set forth. sistanoe of said spring substantially as set In witness whereof We have hereunto set forth. 1 our hands in the presence of two witnesses. 2.
